Indlela yokuvuza yangaphakathi yevalve? Izilumkiso zokusebenza kwevalvu? Iinkcukacha zokupeyinta ivalvu kunye nokumakishwa
1, misela indlela yokuvuza kwevalve yangaphakathi emva kokuba ivalve ivalwe iiyure ezi-4-6, sebenzisa ithemometha ye-infrared ukulinganisa isiqu (kufuphi nomzimba wevalvu) okanye i-150mm ezantsi komsinga weqondo lobushushu lentsimbi yomzimba, elingaphezulu kwe-70 ℃, ichongiwe “njengokuvuza kwangaphakathi”. Le ndlela isetyenziswa kwiivalvu ezininzi zangaphakathi ezivuzayo. Kodwa kumsebenzi wokwenene, siye sadibana namatyala akhethekileyo alandelayo
1) ngenxa yokuma kofakelo lombhobho, kukho iivalve phambi nasemva kokuphazamiseka komphunga wobushushu obuphezulu, njengokuqhagamshelwa kuxinzelelo lombhobho, umbhobho wejellyfish.
Okokuqala, umgangatho wokumisela ukuvuza kwevalve
1, misela indlela yokuvuza kwevalve
Emva kweeyure ezi-4-6 zokuvalwa kwevalve, sebenzisa i-thermometer ye-infrared ukulinganisa ubushushu bentsimbi kwisiqu (kufuphi nomzimba) okanye i-150mm emazantsi omlambo, ukuba mkhulu kuno-70 ° c, kuthathwa "njengokuvuza kwangaphakathi". Le ndlela isetyenziswa kwiivalvu ezininzi zangaphakathi ezivuzayo.
Nangona kunjalo, kumsebenzi wethu osebenzayo, siye sadibana nezi meko zikhethekileyo zilandelayo:
(1) Ngenxa yokuma kofakelo lombhobho, kukho ezinye izivalo phambi nasemva kokuphazamiseka komphunga wobushushu obuphezulu, ezinjengokuqhagamshelwa kwidrain yoxinzelelo, isicupho sombhobho wejellyfish okanye umnyango wokuhambisa amanzi, ezi zivalo nokuba ziyavuza ziqinile, isivalo. ubushushu besiqu buya kuba ngaphezulu kwe-70℃.
(2) Ukungena ngecala kumnyango womgibe okanye umnyango wokuhambisa amanzi omgibe kunye nombhobho wejellyfish. Xa indawo yevalvu ikufutshane kumbhobho oyintloko, okoko nje nayiphi na ivalve yesebe kumbhobho ivuza, ubushushu bezinye iivalvu buya kunyuka bube ngaphezu kwe-70℃, njengevalve yebhoyila yokudonsa, idreyini eshushu kakhulu, njl.njl. Ngoko ke, UKUMISELWA kokuvuza NGAPHAKATHI KWEZI VAVAVU KUFUNEKA KWENZIWE NGEZINYE IINDLELA, NJENGOKUBA KULINGANISELA UBUDONGA WODONDA LOMNYANGO OKANYE UBUDLUNGU BOMNNGO WANGAPHAKATHI UKUMISA UKUVUZA NGAPHAKATHI.
Okwesibini, umsebenzi wevalvu ubalulekile ofuna ukuqwalaselwa
1. Kwiingcango ze-manual yamanzi e-drainage ye-thermal system, kufuneka ziqiniswe kwakhona isiqingatha seyure emva kokugqitywa komsebenzi ukuphelisa i-gap ye-valve ebangelwa ukwanda kwe-thermal kunye ne-cold contraction.
2. Ngombhobho wokushisa ngomnyango omnye okanye ezimbini, ukulandelelana komsebenzi wevalve ngolu hlobo lulandelayo: vula umnyango kanye ngaphambi kokuvula umnyango kabini; Xa uvala, kufuneka uqale uvale umnyango kabini uze uphinde uvale umnyango.
I-3, ekusebenzeni kwevalve yesango, inokuvalwa ngokupheleleyo okanye ivuleke ngokupheleleyo, ungavumeli isiqingatha esivulekileyo sesigxina esivaliweyo, ukwenzela ukunciphisa umonakalo wokuvuthela kwivalve.
Okwesithathu, ulawulo lwevalvu lubalulekile olufuna ukuqwalaselwa
Iyunithi 1, ngaphambi kokuqala kombane ngamnye, uvavanyo lwevalve yepneumatic, inkqubo yovavanyo, kufuneka ibe yingcali kwindawo yokubeka iliso kwivalve kunye nemeko yokunyakaza kwe-damper, khangela intonga yokudibanisa i-actuator kunye nepini kufuneka ingabikho ukukhululeka, ukugoba nokuwa, khangela imiyalelo yokuvulwa kwe-DCS kunye ne-in situ kufuneka ihambelane, kukho umnyango wombane wokumisa ophakathi ukuvavanya ukumisa okuphakathi kuqhelekileyo. Lungisa isalathiso sokutshintsha kocango sichanekile, isenzo esiguquguqukayo, kunye nelophu edibeneyo ukuya kuvavanyo olufanelekileyo lobuchwephesha, uvavanyo lwesixhobo sohlengahlengiso lwe-pneumatic kufuneka lube bhetyebhetye, akukho kuvuza kunye nesenzeko esingaqhelekanga, uvavanyo kufuneka luyeke uvavanyo xa lungaqhelekanga, lwazise kwangexesha abasebenzi bolondolozo ukuba bajongane. nge.
Iyunithi yesi-2, ixesha ngalinye uqala kufuneka lihambelane ngokungqongqo kunye nezibonelelo zokusebenza ezihambelanayo, isango lamanzi iShuFang kufuneka lijonge ukuvalwa ngummiselo, i-watergate nganye yeShuFang ivaliwe (iiyure ezili-10) emva kweeyure ezingama-6, emva kwesango lamanzi. Isalathisi sobushushu be-hydrophobic, kufuneka sisekelwe kumbhobho wevalve emva kokuhlalutya kunye nokugweba ukuba ukuvuza kwevalve, ubushushu obubonisa ukuba akukho bushushu bubonisa ukuba bubhityile emva kwe-watergate, Ithemomitha ye-infrared isetyenziselwa ukulinganisa ubushushu bombhobho wangaphambili kunye neendonga zangasemva ivelufa okanye ukuvaleka ukuze kubonwe ukuba ivalve iyavuza na. Okufana nokuvuza kwevalve yombane okanye yepneumatic, kufuneka ivalwe umnyango wombane we-hydrophobic okanye umnyango we-pneumatic wocango wokuzihlukanisa, ucango lombane lwe-hydrophobic, umnyango we-pneumatic ngaphandle kocango lokuzihlukanisa ngesandla, olufana nokuvuza, kufuneka lushukunyiswe ukuvala umnyango wombane, kwaye ulahlekile kunye nokunxibelelana. unyango lwesondlo. Okufana nokuvuza kocango lwemanuwali, unyango olulahlekileyo kunye nokunxibelelana nokugcinwa.
I-3, ixesha ngalinye ngaphambi kokuvala iyunithi, iziphene ze-valve (ukuvuza) kufuneka zihlolwe, i-valve yokuvuza kufuneka ifakwe kwaye yazise isebe lokulondoloza elifanelekileyo.
4. Kwinkqubo yokuvula kunye nokumisa okanye ngenkqubo yokukhupha uxinzelelo, emva kokuvula isango lamanzi (ukukhupha) isango lamanzi, khangela ukuba kukho ukushisa emva kwevalve okanye i-throttle hole (umgibe), ukuqinisekisa ukuba inokudlala indima i-drainage (ukukhutshwa) amanzi, ukuthintela umhlwa obangelwa ngumbhobho wobushushu wamanzi obangelwa kukuvaleka kwevalve okanye umbhobho okanye umngxuma wokutyhutyha (umgibe).
I-valve PAINTING NOKUMAKITHA UMGAQO UKUBA ISIQINISEKISO SESIXHOBO SIYA KUPAYITYWA EMBUSWENI ONGESEMTSHINI WOMZIMBA WEVALVI NEBHNNETHI, KWAYE UKUCHANISWA KOMBUSO UKUTYINJWA KUYA KUPAYINTWA KWISANDLA SOKUTHUTHUMELA, KWISIPHANSI SOKUPEYINTA, NEBHANWE NJENGOKO KUCHAZIWE KULE THEYIBHILE ENGAPHANTSI. Umbala wepeyinti wendlela yokuhambisa uchazwe ngolu hlobo lulandelayo: isixhobo sombane, uhlobo oluqhelekileyo olupeyintwe grey; Isithathu kwinto enye (yangaphandle, into engenakugqabhuka, ichasene nomhlwa) uhlobo olupeyintwe luhlaza okwesibhakabhaka; I-pneumatic, ihydraulic, ukuhanjiswa kwegiya kunye nezinye iindlela zokuhambisa ezinombala wemveliso yevalvu.
1. Ukuchongwa kwamalungu evalvu
Kwiqokobhe levalve yevalve, kukho umgca othe tye onotolo. Amanani angaphezulu komgca othe tye abonisa inqanaba loxinzelelo lwegama, kwaye ezinye zibonisa iparamitha yeqondo lokushisa kunye noxinzelelo lokusebenza. Umzekelo, i-PNl0 kunye ne-PT510 zisetyenziswa phantsi kweeparamitha zokusebenza ze-10MPa kunye ne-510℃. Inani elingaphantsi komgca othe tye libonisa ububanzi begama lombhobho wokudibanisa.
→ ibonisa ukuba ivalve ithe tye, ukungena phakathi nendawo yokuphuma kwicala lokuphuma, kumgca osembindini ofanayo okanye onxuseneyo.
I-Chrysene > ibonisa ukuba inxalenye yevalve luhlobo lwe-angle ekunene, i-medium isebenza kwindawo yokuvala.
Ibonisa ukuba ivalve inendlela-ntathu kwaye i-medium ineendlela ezininzi zokuhamba.
